Maybe getting into a type of lizard soon??

Depends on price.
You could get a Chinese water dragon as a baby, or a Caiman Lizard for something out of the norm... but they can be pricey.
Also, are you looking on getting one you can touch or one to just look at? Because then almost all monitors are out, lol.
chameleons are pretty cool,

Both Chinese water dragons and Caiman lizards get FAR too big for a 75 gallon aquarium. Even dwarf monitors need more space than a 75 can provide. I have my Ackie in a 150x100x80cm terrarium and hes only maybe 50cm head to tail. You have to take into consideration not just the size but also how active the animal is.
